pvtend.auto_prenorm

pvtend.auto_prenorm(fields: list[ndarray], mask: ndarray | None = None) → list[float][source]

Compute per-event pre-normalization constants.

Each constant is 1 / P95(|field|) over the masked region, so that the pre-normalized field has O(1) magnitude.

Parameters:

  • fields – List of raw SI-unit basis fields.

  • mask – Optional boolean mask (True = include).

Returns:

List of scale factors, one per field.
